How have some of the organisms that live near shore zone adjust to tidal patterns?

Organisms in the near shore zone have developed various adaptations to cope with tidal patterns. Many species, such as barnacles and mussels, can close their shells to retain moisture during low tide, preventing desiccation. Others, like certain fish and crabs, time their feeding and reproduction activities to coincide with high tide when food is more abundant. Additionally, some plants, like salt marsh grasses, have specialized root systems to withstand varying salinity and water levels.
